When I was a "young person" and didn't know any better, I experimented with my BSA Meteor to see if it could be used as a mini shotgun. I cut up lead pellets into fragments and held them all together with asbestos.
In those days, in the 1950s and 60s we had no idea that asbestos was bad for you, and Rawlplug used to market a kind of asbestos fibre that you could buy in a tin, like a 2oz tobacco tin. It was useful stuff for fixing screws into a wall, if the hole was too ragged for a conventional Rawlpug, and they were fibre at the time, not plastic.
You would mix a pinch of the fibre together with a few drops of water, it would consolidate into a mush that you would press into the hole, and then allow it time to dry before inserting the screw.
My best mate's dad was a keen DIY man although we didn't call it DIY as such; Ernie had loads of fascinating tools and kit like blowlamps and the apparatus to make wiped lead joints, a skill to behold in wonderment.
Sorry I digress. This fibre stuff was ideal as a carrier medium for my shot, and Ern was kind enough to let me have some from his tin.
It didn't have much strength of course, and acted just like wadding, falling away from the shot fragments.
Did it work? Well, the Meteor was good for about 9 ft.lb if you were lucky. I think I managed to get my shot to make tiny holes in a sheet of paper at about 4 or 5 yards range, so this was hardly going to qualify as a weapon of mass destruction.
Edit: maybe it got closer than Blair did.
